Colin Ian King 554b117e8f scsi: FlashPoint: Remove redundant variable bm_int_st 
The variable bm_int_st is assigned a value but it is never read. The
variable and the assignment are redundant and can be removed.

Cleans up clang scan build warning:

  drivers/scsi/FlashPoint.c:1726:7: warning: Although the value stored
  to 'bm_int_st' is used in the enclosing expression, the value is never
  actually read from 'bm_int_st' [deadcode.DeadStores]

FlashPoint.c -- FlashPoint SCCB Manager for Linux
This file contains the FlashPoint SCCB Manager from BusLogic's FlashPoint
Driver Developer's Kit, with minor modifications by Leonard N. Zubkoff for
Linux compatibility. It was provided by BusLogic in the form of 16 separate
source files, which would have unnecessarily cluttered the scsi directory, so
the individual files have been combined into this single file.
